1756-IH16I Allen Bradley 16-Channel Isolated Input Module

1756-IH16I Allen Bradley 16-Channel Isolated Input ModuleProduct Overview The Allen Bradley 1756 IH16I functions as a high voltage discrete input module for the ControlLogix platform. This single slot module provides 16 individually isolated input points that sense 125V DC status signals from field devices like limit switches, circuit breaker auxiliary contacts, and pushbutton stations. Because it offers true channel to channel isolation, engineers can wire disparate DC electrical circuits into a single

it does not wear out over time

This passive cooling design ensures the 16 MHz CPU operates reliably even in high-ambient temperature environments

Attribute Technical Data Manufacturer ABB (Asea Brown Boveri) Part Number IMHSS03 Control Interface Servo Valve / I/H Converter System Backplane INFI 90® DCS Processor Synergy IMMFP01

Backplane Current Requirement: 2500 mA

providing the critical communication link between redundant CPU racks and remote I/O stations

specifically optimized for small-to-mid-scale automation projects that demand robust networking and a reduced panel footprint

Model Number: 3500/94

This delay effectively filters out high-frequency transients and contact bounce commonly found in mechanical AC switches

This dual-port fiber optic interface enables deterministic

If the module detects an overspeed condition

It serves as the primary intelligence for optimizing load distribution across multi-generator arrays

preventing localized voltage sag when high-density digital and analog sub-modules operate concurrently
